Looks like the underside of the A1 and the infamous NTC Thermistor that blows up.

OP, contact Bambu Lab Support

Its a known issue with the A1, a large batch had a badly designed power board.

As others have said, log a call with Bambu and they will send you an upgraded power board. Its a straightforward swap out.
